OMAPL137(DSP)

Naveen Chandra

Hello All,

Currently am working with OMAPL137 and using only the DSP core also am masking the ARM9 core. So, i have planned to implement to algorithms on my DSP. Am getting the data from my MCU(SM470). Two algorithms are listed below.

1. Am generating sine wave from MCU and sending it to DSP via SPI. Inside my DSP am making using of FFT inalgorithm to calculate magnitude and phase of the sine wave.

2. Am generating sine wave from MCU and adding noise to it and then sending it to DSP via SPI. Inside my DSP am making use of FIR algorithm to remove the noise.

Please do let me know whether am doing things correctly or not??

Also, please do tell me name of other algorithms or other tasks which i can use inside my DSP.?? I need to make use of my DSP efficiently and load it nearly 80% of the time.

Waiting for your valuable inputs at the earliest.

Thanks and Regards

Hi,

Thanks for your post.

For C674x device, please check the supported kernel functions for C674x DSP_LIB from the below wiki:

http://processors.wiki.ti.com/index.php/C674x_DSPLIB#DSPF_sp_fir_gen_.28FIR_Filter.29

For fixed point computation, the C674x core is fully compatible with the C64x+ DSPLIB, kindly check the c64x+ DSP library programmer's reference as below:

http://www.ti.com/lit/ug/sprueb8b/sprueb8b.pdf (please check Table 3 -5)

For downloads of c66x, c67x, c64x, c64x+ & c674x DSP LIB, kindly refer the below link:

http://www.ti.com/tool/sprc265

After installing c674x DSP LIB., you could see the FIR filter example .CCS project in the below specified path:

~\dsplib_c674x_3_2_0_1\packages\ti\dsplib\src\DSPF_sp_fir_gen\c674\DSPF_sp_fir_gen_674LE_LE_COFF\

Kindly refer the above example.

Thanks & regards,

Sivaraj K
